Abstract： |
The invention relates to the moving article positioning error correcting system. The error correction system and moving tracking method for vehicle positioning comprises single chip controller controlling input and output, receiving moving parameter data required to correct, sending orders to execution mechanism, image acquiring system for acquiring continuous digital image data, running tracking system executing the running tracking algorithm based on image data execution, deciding actual running parameter, judging whether current moving status needs to be corrected and sending out the running parameters to be corrected to the control system. It starts with receiving image data, searching shared parts of two images or objects to decide the matching feature pair, calculating actual running parameter based on matching features, deciding the existing moving status of based on the relative movement of the vehicle, and deciding whether the existing running status can be recorded into the running track for continuous moving parameters. |
